No me alcanzo todo para ponerlo todo acá pongo la otra parte:

private class MouseListener extends MouseAdapter {

Toolkit tk = Toolkit.getDefaultToolkit();

Cursor zoommenos = tk.createCustomCursor(cursormenos, new Point(centerPanel.getX(), centerPanel.getY()), "Alejar");


public void mouseClicked1(MouseEvent event) {

}

movex = 0;
movey = 0;
repaint();
} else {
if (event.getButton() == MouseEvent.BUTTON1) {
centerPanel.setCursor(zoommas);
zoom += 0.5;
x = (int) (x - (event.getX() * 0.5));
y = (int) (y - (event.getY() * 0.5));
} else {
centerPanel.setCursor(zoommenos);
zoom -= 0.5;
x = (int) (x + (event.getX() * 0.5));
y = (int) (y + (event.getY() * 0.5));
}
repaint();
}
} else {
select((ImagePanel) event.getComponent());
}
}
//Fin Zoom Imagen

//Aparece lupa con solo hacer click en el boton
@Override

centerPanel.setToolTipText("ALT + Clic: Tamaño original");
} else {

}
}
//Fin Aparece lupa
}
}
